WebConnector 2.0.0

WebConnector 2.0 adds a public Java API and a shared action service, persistent operations with idempotency keys, scoped authentication, typed validation, and signed webhook delivery with retries.

• One Java 17-compatible JAR targets Paper 1.20.1–26.2; 26.3 compatibility is experimental.
• API keys support names, expiry, action scopes and permissions, with IP/CIDR rules and bounded request/operation limits.
• HTTP clients can submit actions, retain request/operation IDs and poll asynchronous results.
• Idempotency reservations survive restarts. Interrupted work is recorded for reconciliation instead of being automatically repeated.
• Java plugins can register private actions, explicitly publish HTTP endpoints and emit webhook events through Bukkit ServicesManager.
• English documentation, Russian guides, OpenAPI, Java/Skript examples and a Paper smoke-test harness are included.

Upgrade

Version 1 configuration requires migration. Empty secrets, unrestricted JSON interpolation and unrestricted file deletion are no longer accepted. The old configuration is left unchanged. Read the migration guide.

The default configuration binds to localhost, generates a private secret and enables only ping. Shutdown and file deletion remain opt-in. Timeouts and command failures can leave partial external effects; retain the original idempotency key and reconcile before creating a new operation.

The automated suite uses real HTTP requests and mock webhook receivers across the 1.20.1/1.20.6/1.21.11/26.2/26.3 API matrix. API/runtime tests do not certify every live Paper or third-party Skript addon combination; see testing.
